Abstract

We present in this article a fourth-order integrated LC bandpass Delta-Sigma modulator for direct conversion of high intermediate frequencies. It is designed in a 0.25 μm BiCMOS SiGe:C process from STMicroelectronics. The modulator is able to direct digitize a 1GHz IF signal in a 20MHz bandwidth. The continuous-time loop filter employs two integrated LC resonators with active Q?enhancement circuits. A multi-feedback architecture is used to achieve higher order noise-shaping, while maintaining the modulator stability. A multibit quantizer was implemented to reduce quantization noise and improve stability.
